Paper Abstract

UV light from an Excimer laser operating at 248 nm with fluence of 800 mJ/cm2 per pulse at 30 Hz repetition rate is used for writing process of a fiber Bragg Grating (FBG). Multiple FBGs with different center wavelength and reflectivity are produced by varying strain and exposure time on a single strand of a SMF where 1552.75 nm is the center wavelength of the unstretched FBG. The in-situ measurement of the reflectivity, bandwidth and center wavelength of each Bragg grating will be described. We will also present an RF technique for measuring the separation between two adjacent FBGs.
